The Perceived Value of Cybersecurity Analyses and Frameworks for an IT Company
2021
Master's thesis in Cyber security (IS507) Recent trends show an increasing rate of cyberattacks against private companies and public organizations. Existing cybersecurity analyses and frameworks offer a set of guidelines for preparedness and security countermeasures against cyberthreats. However, there is little knowledge on the perceived value of these. This thesis explores the value of common cybersecurity analyses and frameworks, to understand their values for the organizations looking for a holistic overview of the possible countermeasures against cyberattacks. A choice made for the study was to mainly focus on IT companies as cases. To address the challenging nature of the thesis topic…
Norovirus-Host Interactions in the course of Inflammatory Bowel Disease
2021
Inflammatory bowel disease (IBD) affects around 200,000 people in France. This group of conditions includes Crohn's disease (CD), which involves the entire digestive tract, and ulcerative colitis (UC), which involves only the colon and rectum. It is known that immunological, genetic and microbiological factors are at play in IBD, but the role of viruses remains only partially explored. Among viral etiologies, human noroviruses (huNoV) are the main cause of acute viral gastroenteritis worldwide. Norovirus binds to intestinal cells through histo-blood group antigens (HBGA), including ABO and Lewis antigens. The expression of HBGA is dependent upon tissue type and the underlying physiopatholog…

The nickel-support interaction as determining factor of the selectivity to ethylene in the oxidative dehydrogenation of ethane over nickel oxide/alum…
2021
[EN] Nickel oxides supported on gamma-alumina (Ni-loading from 5 to 30 wt% NiO) have been synthesized and tested in the oxidative dehydrogenation (ODH) of ethane in order to determine the importance of the NiO-support interaction. The best performance was achieved by the catalyst with 15 wt% NiO; higher NiO-loadings lead to the formation of unselective bulk-like NiO and lower Ni-loadings present high proportion of free alumina surface sites. The presence of oxalic acid and/or niobium in the synthesis gel resulted in the formation of NiO particles with similar size, but higher crystallinity and reducibility than the standard 15 wt% NiO catalyst. The obtained results have revealed that, in ad…
Outdoor activities and motor development in 2–7-year-old boys and girls
2021
Problem Statement: Parents of young children favor indoor activities for their children, because staying inside supports comfortable daily routines in the family timetable, safety issues and clothing. However, playing outdoors supports children’s development, offering multiple challenges to overcome and the possibility to learn new skills. Approach: Based on Gibson’s theory of affordances (1977), outdoors can be seen as an excellent learning environment for children to reach the zone of proximal development (Vygotsky, 1987). Purpose: This paper describes Finnish nature and four seasons as an environment to support children’s motor development and inspire outdoor playing. The Skilled kids pa…
Setting Individual Goals for Pupils with Profound Intellectual and Multiple Disabilities : Engaging in the Activity Area-Based Curriculum Making
2021
The activity area-based curriculum model (AACM) is used in the Finnish basic education to support pupils—most of whom have profound intellectual and multiple disabilities (PIMD)—who could benefit more from skills that advance independent life coping. Existing studies have concentrated mainly on the Individual Education Plan (IEP) goal-setting process for pupils with milder disabilities than PIMD and have consistently demonstrated significant barriers in the process. This study explores the collaborative IEP goal-setting process for pupils with the AACM. Sixty-five Finnish special education teachers using the AACM participated in the study. Semi-structured interviews were analysed with thema…
Zero-field NMR of urea : spin-topology engineering by chemical exchange
2021
Well-resolved and information-rich J-spectra are the foundation for chemical detection in zero-field NMR. However, even for relatively small molecules, spectra exhibit complexity, hindering the analysis. To address this problem, we investigate an example biomolecule with a complex J-coupling network─urea, a key metabolite in protein catabolism─and demonstrate ways of simplifying its zero-field spectra by modifying spin topology. This goal is achieved by controlling pH-dependent chemical exchange rates of 1H nuclei and varying the composition of the D2O/H2O mixture used as a solvent. Specifically, we demonstrate that by increasing the proton exchange rate in the [13C,15N2]-urea solution, the…
Key advantages of the leverage points perspective to shape human-nature relations
2021
This perspective paper synthesises the special issue 'Human-nature connectedness as a leverage point for sustainability transformation'. Based on the articles in this special issue, we aim to foster the operationalisation of the leverage points perspective to shape human-nature relations to enable sustainability transformations. Specifically, we draw on four key advantages of the leverage points perspective: (i) the explicit recognition of deep leverage points; (ii) the ability to examine the interactions between shallow and deep system changes; (iii) the combination of causal and teleological modes of research; and (iv) the ability to function as a methodological boundary object. The contr…

L'anima dei viventi tra conflitto e unità
2021
Le scoperte biologiche degli ultimi decenni, insieme alle stesse fondamenta teoriche della teoria dell'evoluzione, suggeriscono un'immagine dinamica della vita, intesa come un processo di continua riorganizzazione. Anche una parola antica come “anima”, per essere riproposta all'interno di uno scenario di tale sconvolgente profondità, necessita di una nuova riorganizzazione, basata proprio sui presupposti della biologia contemporanea. In particolare, il dualismo tra competizione tra linee ereditarie alternative e tendenza all'aggregazione di tali linee, riscontrabile in molti dei casi di studio proposti nell'articolo, costituisce un fondamentale motore per la costituzione di sistemi compless…

Mobility Fee—Creating Better Cities, Creating a Better Future!
2021
The following paper explores an alternative to financing public transportation in densely populated urban areas through ticket sales as a possible incentive to increase the usage of public transportation with the intent of reducing car traffic and pollution in urban spaces. It addresses the option of collecting a “mobility fee” from residents of an area to replace the revenue generated by ticket sales. Since the fee as it is envisioned in this paper would be collected from residents regardless of whether they actually use public transportation, this method would result in the usage of public transportation itself not being associated with any additional monetary cost. The text elaborates on…
Are electric vehicles eco-friendly products? A review from life cycle and sustainability perspective
2021
Industry, especially the automotive industry is permanently changing and adapting to the external and internal factors. The appearance of the new types of vehicles – electric vehicles, is a big and important step not only regarding the evolution of the product, but also regarding the advantages of reducing environmental impact. It is promoted the idea that an electric vehicle generates less direct emissions in use phase compared with a conventional one. If we limit to this, we could say that we are dealing with an eco-friendly type of vehicle. The question is, can we extend this idea to the other stages of the life cycle? What about the sustainability of the industry? This article highlight…

CMC is more than a measure of corticospinal tract integrity in acute stroke patients
2021
In healthy subjects, motor cortex activity and electromyographic (EMG) signals from contracting contralateral muscle show coherence in the beta (15-30 Hz) range. Corticomuscular coherence (CMC) is considered a sign of functional coupling between muscle and brain. Based on prior studies, CMC is altered in stroke, but functional significance of this finding has remained unclear. Here, we examined CMC in acute stroke patients and correlated the results with clinical outcome measures and corticospinal tract (CST) integrity estimated with diffusion tensor imaging (DTI). During isometric contraction of the extensor carpi radialis muscle, EMG and magnetoencephalographic oscillatory signals were re…

Obstructive Malformations of the Internal Jugular Vein
2021
Obstructive malformations of the internal jugular veins represent a relatively new clinical problem, which as of yet has not been fully understood. In normal subjects, the internal jugular vein is valveless, except for a single valve, situated just above the junction of this vein with the brachiocephalic vein. Usually, normal jugular valves exhibit a two-leaflet structure. Stenotic lesions of these veins were described for the first time in 2009 in a group of multiple sclerosis patients. The most common obstructive malformation of the internal jugular vein is a stenotic valve. There are several morphological types of such aberrant valves, comprising annular stenoses, valves with fused, reve…

Master´s thesis in Advanced Teacher Education Background: Idioms can be considered as an interesting, but complex linguistic phenomena, which occurs frequently both in written and spoken language. Idioms can be found in a variety of different texts, such as papers, debates, speaks etc. Despite being frequent in the language, little attention has been paid to idioms in school and in the Norwegian subject in high school. Previous research shows that students have little knowledge of and lack basic understanding of idioms. Never the less, more focus should be paid to high school students’ knowledge of idioms. To gain knowledge of how high school students understand idioms, and what factors tha…

Road verges provide alternative habitats for some, but not all, meadow plants
2021
Questions Agricultural intensification has led to the decline of biodiverse meadows and other semi-natural grasslands. Road verges offer potential alternative habitats for meadow species, but they may not be suitable for all meadow species due to different soil properties, frequent disturbances, pollution or suboptimal management. Are the communities of vascular plants and bryophytes similar or dissimilar to those in mown or grazed meadows? What kind of species are associated with road verges, mown meadows or grazed meadows? How do the habitat types differ in their soil conditions and disturbance intensity? Location The study was conducted on 36 sites in Central Finland. Methods We compared…

From Clinical Imaging to Patient-Specific Computational Model: Rapid Adaptation of the Living Heart Human Model to a Case of Aortic Stenosis
2021
Aortic stenosis (AS) is the most common acquired heart valve disease in the developed world. Traditional methods of grading AS have relied on the measurement of aortic valve area and transvalvular pressure gradient. Recent research has highlighted the existence of AS variants that do not meet classic criteria for severe AS such as low-flow, low-gradient AS. With the development of sophisticated multi-scale computational models, investigation into the left ventricular (LV) biomechanics of AS offers new insights into the pathophysiology that may guide treatment decisions surrounding AS. Building upon our prior study entailing LV-aortic coupling where AS conditions were applied to the idealize…
Image-based 3D reconstruction using traditional and mobile-phone data-sets for road pavement distress analysis
2021
The issue of road networks being in deplorable conditions is one that is widespread globally. One of the main precursors for this is that when preparing maintenance management systems, many road agencies rely on data which is often outdated or inaccurate. This is due in many cases to insufficient budgets which are unable to adequately address both maintenance and rehabilitation. It is therefore critical that road agencies have better tools at their disposal to help combat these issues. One of the possible techniques that have been identified is the use of structure from motion techniques to adequately identify road pavement distresses. This paper advances previous work in this area and expl…
